Description

technical field [0001] The invention relates to the field of intermediate frequency signal processing, and mainly relates to an intermediate frequency signal processor and an intermediate frequency signal processing system. Background technique [0002] The intermediate frequency signal is a common processed signal in the field of signal processing. The common processing device adopts the AD processing circuit to sample it, convert the intermediate frequency signal into a digital signal, and then digitalize it through the signal processing circuit of the FPGA and the main control circuit. After processing by the algorithm, the digital signal is sent through the network interface. [0003] In the existing technology, such as figure 1 As shown, the AD processing circuit, FPGA signal processing circuit, and main control circuit are often integrated into a PCB board. This design generally has the following technical problems. [0004] 1. This design causes the area of ​​the P...

AI Technical Summary

Problems solved by technology

[0004] 1. This design causes the area of ​​the PCB board to be too large, and the position of the main processing chip in the PCB board is relatively random; when this device is placed in the vehicle environment, its vibration environment is more complicated, so it is easy to cause its The PCB board card is damaged due to uneven force

[0005] 2. This kind of equipment generally only provides an external output interface by the main processing chip of the main control circuit

Such a design is in a complex vehicle environment. Once the main control CPU fails, the command center will not be able to obtain data, and its combat readiness is poor.

[0006] 3. The existing equipment generally uses a single FPGA to operate, resulting in low efficiency of the entire data transmission, and the transmission bandwidth is not enough to support large-capacity data transmission

[0007] 4. The device power consumption of the existing integrated board has not been optimized, and the layout of the device has not been properly set, resulting in uneven power consumption and uneven heat generation on the board surface. Therefore, it needs to be equipped with a complex-shaped cooling plate, resulting in The processing cost is very high, and it is difficult to complete the whole page heat dissipation in the chassis
